Question

On a number line which integers are shown on the left side of the number line?
A.Negative
B.Positive
C.Both
D.None of these

Answer 1

Hint: We know the number line, draw a number line and check the number will come on the left side .

Complete step-by-step answer:

Arithmetic operations of numbers can be better explained on a number line. To begin with, one must know to locate numbers on a number line. Zero is the middle point of a number line. All (natural numbers) positive numbers occupy the right side of the zero whereas negative numbers occupy the left side of zero on the number line.
As we move on to the left side value of a number decreases. For example, $1$ is greater than $-2$. In a number line, integers, fractions, and decimals can also be represented easily. Check out the links given below to learn more.
When we add two positive numbers, the result will always be a positive number. Hence, on adding positive numbers direction of movement will always be to the right side. When we add two negative numbers, the result will always be a negative number. Hence, on adding negative numbers direction of movement will always be to the left side. A set of integers include zero, positive numbers and negative numbers excluding fractions. Even though arithmetic operations apply to integers, the rules for the addition and subtraction of integers are different.
When we subtract two positive numbers, move to the left as far as the value of the second number. When we subtract two negative numbers, move to the right as far as the value of the second number.
So here we can see that at the right side on the number line there are positive integers and that on the left is negative integers.
On the number line negative integers are shown at the left side.
Therefore, the correct answer is option (A).

Note: Zero is the middle point of a number line. All (natural numbers) positive numbers occupy the right side of the zero whereas negative numbers occupy the left side of zero on the number line.
